GEORGE l. WIGGINTON, 0F KALAMAZOO, MICHIGAN, ASSIGNOR TO KALAMAZOO LOOSE LEAF BINDER 00., OF KALAMAZOO, MICHIGAN.

TEMPORARY BINDER.

Application filed February 10, 1916.

To all whom it may concern:

Be it known that I, GEORGE P. VVIGGIN- TON, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

This invention relates to improvements in temporary binders.

The main objects of this invention are:

First, to provide in a temporary hinder or loose sheet holder an improved adjusting mechanism.

Second, to provide in a temporary binder or loose sheet holder an improved adjusting mechanism which is capable of rapid and easy adjustment.

Third, to provide an improved temporary binder or loose sheet holder which is capable of rapid manipulation to permit the insertion or removal of sheets or leaves and one which is automatically retained in its adjusted positions and at the same time is readily freed to release the sheets.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a detail inside plan view of a structure embodying the features of my invention with the covers extended, the leaves being shown in an upright position.

Fig. II is an inverted detail view of the adjusting mechanism of the embodiment shown in Fig. I.

Fig. III is an inverted view similar to that of Fig. II, with the clutch roller support or housing shown in section.

Fig. IV is an enlarged detail section on a line corresponding to line 44 of Figs. I, II and III.

Fig. V is a plan view of the blank from which the clutch housing or support is formed.

Fig. VI is a detail inside plan view similar to that of Fig. I of a modified formuof Specification of Letters Patent.

Patented June 26, 191?. Serial No. 77,495.

my invention, the clutch roller being spherical instead of cylindrical as shown in Fig. III, the parts being correspondingly modified to accommodate such a roller.

VII is an inverted detail view of the ad usting mechanism of the structure shown in Figs. I and VI.

Fig. VIII is a detail section on a line corresponding to line 88 of Figs. VII and IX.

Fig. IX is an enlarged detail section on a hne corresponding to line 9-9 of Fig. VII.

Fig. X is a detail plan view of the blank for the clutch roller support or housing of the embodiment shown in Figs. VI to IX, inclusive.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the covers 1 and 2 are preferably provided with clamping bars or members 3 pivotally connected thereto as shown in my Patent No. 1,022,452, issued April 9, 1912. Binding members 4, preferably in the form of flexible strips, extend between the covers, being connected to the cover 1 at 5 and to the cover 2 through my improved adjusting mechanism. The cover 2 is provided with a recess or chamber 6 in which the adjusting mechanism is disposed.

My improved adjusting mechanism comprises a cross head or adjusting member 7 to which the binding strips 4: are connected. The adjusting member 7 is slidably mounted on the bar 8 disposed longitudinally of the cover The adjusting member is held in its adjusted positions on the bar by means of a clutch which consists of a clutch member 9, preferablya roller or cylindrical in form, supported on the adjusting member 7 to coact with the bar 8. This clutch member is supported by a housing 10 having-a way portion 11 disposed at an angle to the bar 8 so that when the clutch member is adjusted in one direction it is carried against the bar with a clutching or gripping action.

A spring 12 is mounted to carry the roller to its bar engaging or clutching position.

A lever 13 is pivotally mounted on the ad justing member at 14 to project into th housing and engage the roller for carrying it from its clutching or bar engaging position, thereby releasing the adjusting memher so that it slides freely on the bar. Thls lever is preferably arranged so that its end projects from the edge of the adjusting member in which position it may be grasped simultaneously with the adjusting member so that the adjusting member may be released and moved along on the bar. adjusting member may, however, be moved outwardly or toward the outer end of the cover without releasing the clutch. At the same time, the clutch effectively holds it against return movement.

The lever 13 is returned to its initial or inoperative position against the stop 13 by the spring 15 mounted on the pin 16.

The housing 10 is preferably a sheet metal stamping formed from a blank, as shown in Fig. V.

In the embodiment shown in Figs. VI to X inclusive, the clutch member 17 is spherical instead of cylindrical. The housing or support 18 is mount-ed to embrace the bar, the clutch member 17 engaging the side of the bar instead of its edge as in the other embodiment illustrated. A. coiled spring 19 urges the clutch member to its engaging position.

The releasing lever 13 is substantially th same as that shown in the embodiment first described.

The housing 18 is preferably a sheet metal stamping, the blank being shown in Fig. X.

This housing has an opening 20 through which the disengaging lever 13 pro ects.

The operation of this modified structure is the same as that of the structure shown in Figs. I to V inclusive.

By this arrangement of parts I secure a mechanism which is simple and compact and at the same time one which is very effective and convenient to use and is strong and durable.

I have not attempted to illustrate certain further modifications or embodiments which I contemplate as I believe the disclosure made will enable thos skilled in the art to which my invention relates to embody or adapt the same as conditions may require.

7 Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a temporary binder, the combination with the covers, of binding strips extending between the covers, a bar disposed longitudinally of one of the covers, an adjusting member to which said binding strips are connected slidably mounted on said bar, a clutch roller, a support for said roller disposed on said adjusting member at an angle to said bar so that said roller is carried into clutching engagement with the bar when moved in one direction, a spring for actuat- The member to coact with said bar for securing the adjusting member in its adjusted positions thereon, a spring for actuating said roller toward its clutching position, and means for disengaging said roller mounted on said adjusting member.

. 3. In a temporary binder, the combination with the covers, of binding strips extending between the covers, abar disposed longitudinally of one of the covers, an adjusting member to which said binding strips are connected slidably mounted on said bar, a friction clutch member mounted on said adusting member to coact with said bar, the clutch engaging movement of said clutch member being toward the outer end of the cover a spring for yieldingly holding said clutch member in its engaging position, and manually operated means for releasing said clutch member and holding it'in its disengaged position mounted on said adjusting member.
